Chapter 12, Problem 49E

Interpretation Introduction

(a)

Interpretation:

Whether the element $\text{Br}$ is more electronegative or the element $\text{Cl}$, is to be stated.

Concept introduction:

Electronegativity is a term which describes the tendency of any species to pull the shared pair of electrons towards itself. More is the electronegativity of an element, more is the attraction of electron pairs towards itself. Trend of electronegativity in a period is different from the trend of electronegativity in a group.

Interpretation Introduction

(b)

Interpretation:

Whether the element $\text{O}$ is more electronegative or the element $\text{S}$, is to be stated

Concept introduction:

Electronegativity is a term which describes the tendency of any species to pull the shared pair of electrons towards itself. More is the electronegativity of an element; more is the attraction of electron pairs towards itself. Trend of electronegativity in a period is different from the trend of electronegativity in a group.

Interpretation Introduction

(c)

Interpretation:

Whether the element $\text{Se}$ is more electronegative or the element $\text{As}$, is to be stated

Concept introduction:

Electronegativity is a term which describes the tendency of any species to pull the shared pair of electrons towards itself. More is the electronegativity of an element; more is the attraction of electron pairs towards itself. Trend of electronegativity in a period is different from the trend of electronegativity in a group.

Interpretation Introduction

(d)

Interpretation:

Whether the element $\text{N}$ is more electronegative or the element $\text{F}$, is to be stated

Concept introduction:

Electronegativity is a term which describes the tendency of any species to pull the shared pair of electrons towards itself. More is the electronegativity of an element; more is the attraction of electron pairs towards itself. Trend of electronegativity in a period is different from the trend of electronegativity in a group.
